| Abstract: | An investigation is made to the unstable combustion for combustor, and further for the control purpose a dynamic system and control model is proposed according to the characteristics of the unstable combustion. By means of the feedback linearization procedure of differential geometry, an equivalent, fully controllable and linear model was derived via a homomorphie transformation and a sliding mode controller was constructed for eombustor. Computer simulation results showed the sliding mode controller with well tracking accuracy, rapid response, and strong robustness is efficient in controlling unstable combustion for eombustor. |
